A restructure by oil and gas company Santos will see 100 workers laid off in Adelaide and the Cooper Basin.
The job cuts will include analysts and finance staff, reports the ABC, and they will leave the company in the first half of 2013.
"What's happening is that some of the jobs which were for the traditional way of doing things are no longer required,” James Baulderstone, the head of Santos’s eastern Australia business unit, told The Australian.
"There's never an easy time to do this… We like to provide as much information and be as upfront as we can with our workforce.
"So when we made the decision, we believed it was the right thing to tell our people immediately.”
The company’s restructure will lead to 500 new jobs over the next five years, mainly related to shale gas operations. Santos started producing gas from Australia’s first commercial shale well, in the Cooper Basin, in October.
The Australian reports that none of the sacked workers were members of a union.
